I This invention relates to roller bearings, and at their ends which are rounded as at 7 to conhas for its object, Aa one-piece cylindrical cage form to the rounded surface of the channels 8 for the rollers.. which is particularly simple and of the heads.I economical in construction, -and in which the The slots 2 are preferably of less width than 5 rollers are readily assembled, and the method of the diameter of the rollers. Preferably, the end 5 assembling the rollers in the one-piece cage. faces 9 of the rollers aroundv the axles 6 thrust The invention consistsin the novel features and against the end walls 10 of the slots 2 and thus in the combinations and constructions hereinrelieve the axles -6 from thrusting against the after set forth and claimed. heads,- so that practically the only strain on the In describing this invention, reference is had axles is that required to hold .the rollers from 10 tothe accompanying drawing, in which like charinward displacement. j* i acters designate corresponding parts in all the In aembling the rollers in the one-piece views. sheet metal cage, the rollers are inserted in the Figure 1 is an end view of this roller bearing, cage through the end'thereof at which the dis- !5 partly broken away. placed, or partly displaced, head 4 is located, 15

Figure 2 is a longitudinal sectional view'of this with the axles 6, at like ends of the rollers, in aring. l the groove of the head 3, they being temporarily Figure 3 is afragmentary view, similar to Figheld in this position inany suitable manner. As ure 2, showing one of the heads of the cage disseen in Figure 3, in placing the rollers in the W placed outwardly to permit the assembly of the cage, the rounded axle 6 at one end of each 20 rollers in the cage before the displaced head is roller is seated in the arcuate groove of the head pressed into nal position. 3 which is undisplaced, the roller standing in-v I'his roller bearing comprises a one-piece cage clined. Then the roller is rocked or swung about comprising .a barrel portion formed with roller the transverse axis of the rounded axle 6 in the 5 receiving slots, and integral outwardly extending groove 3 thus carrying the other axle under the 25 annular heads or anges at its ends shaped to displaced head 4. The displaced head is then form channels, rollers in the cage having peforced into its nal position. Owing to this ripheral portions extending into the slots, and arrangement and operation, and due to the axles at its ends extending into the channels oi'- rounded axles 6, but'a small initial displacement l the heads, the heads being rounding, or arcuate, of the head 4 is necessary. When the head or 3,0 in cross section to provide rounding grooves, or flange 4 is forced inwardly into nal position, the channels, and the axles having the ends rounded axles 6 of the rollers are interlocked in the correspondingly. Preferably, the ends of the grooves of the heads, or anges 3, 4. The forcing rollers at the base of theI axles thrust against operation may be performed in any well known i one or the other of the end walls of the roller -manner, as by spinning, or by dies, and the round- 35 receiving slots to relieve the axles from end thrust. ed ends of the axles 6 form abutments, or anvil l The method of assembling the rollers in the surfaces against which the flange or head 4 presses cage consists in forming the cage with the heads, during the forcing operation. Preferably, as but leaving one oi' the heads displaced to permit shown in Figure 3, the flange 4 is but partly disthe insertion of the rollers in the slots and with placed sufliciently to permit the rollers to be 40 the Vaxles at like ends of the rollers in the groove snapped in the ange 4 and thereafter the flange of the head that is not displaced, and then forcing 4 is spun into its iinal position. 0l' Spinning the displaced head htO nal D051- 'Ihis roller bearing is especially economical to `|3011. the mundll' ends 0f the EXIBS Serving as manufacture, in that the cage consists of one abut-ments.
